LBreakout2

Downloading and Installing LBreakout2 via APT/Synaptic: To download and install LBreakout2, just type lbreakout2 in the Find box of the Synaptic main window, click Install Latest Version, click Execute, and then follow the general procedures you learned in Chapter 10.

Running LBreakout2: Once installed, you can run LBreakout2 by going to the Main panel menu and selecting Games > More Games > Linux Breakout 2.  You won't be able to use your mouse for anything else when playing LBreakout2; this is normal, so don't worry. To quit, just hit the Esc key until the game is gone.
